Pilot a submarine through procedurally deeper ocean trenches, collecting resources from defeated enemies while your sub operates offline. Upgrade your vessel and weapons, expand your aquarium collection, and face escalating bosses that gate progression into new depths. Ideal for players who enjoy steady mechanical advancement with minimal active input required.
